Embodiment 9:
The means of defence of the middle net Information Security Defending System described in above-described embodiment, the equipment end of this product is the finger print safety equipment based on crypto chip.When net Information Security Defending System inserts a PC in handle, after operating system, identify a CD-ROM and memory block.
Before carrying out fingerprint login, it is seen that an ordinary mobile storage, it is as broad as long with the movable storage device bought on the market.It can be used as common memory device to use.
In CD-ROM, an exe file can be seen.The management software of message protection system that Here it is.If have employed automatic operation, or with double mouse click it, just can see the program interface of ejection.
Finger print safety memory block carries out login authentication based on the fingerprint of user.Therefore, before the secure storage areas that use one is new, the fingerprint of necessary registered user.
(1) fingerprint management
In a secure storage areas, 10 pieces of fingerprints can be preserved.
When mouse-click left screen fingerprint management button, just enter fingerprint management interface.
If the middle net Information Security Defending System of the fingerprint that has not yet registered, directly interface can be entered.Otherwise system can eject finger print identifying dialog box, asks finger print identifying.Only have by certification, just can enter interface.
In fingerprint management interface, there is the handle icon of 10 pieces of fingerprints.
Click the empty fingerprint icon had not yet registered, will interpolation fingerprinting operation be entered.Otherwise, click chartered fingerprint, then enter fingerprint deletion action.
According to the prompting of program, interpolation or deletion action can be completed easily.
(2) visiting-card management
In secure storage areas, the business card of some contact persons can be preserved.
One or several contact person can be chosen as addressee, for user carries out file encryption.File after encryption, only has encipherer and addressee to decipher.
Contact person can be personal, also can be a group.Therefore, can: encryption only deciphers for oneself the file (not selecting addressee during encryption) checked; For one or more individual or group's encrypt file, only selectively addressee can decipher;
All right: multi-enciphering: such as
Select an addressee A as final addressee, carry out file encryption.
Then select a transfer people B as addressee, the file of encryption is encrypted again.
When file being given B transfer, B can once decipher.But see not isolog.B gives A file again, is undertaken, in this deciphering, obtaining expressly by A.
When opening file more than needs two people (such as paper), this method is very applicable.Triple or more infill layer can also be carried out.
Relay is encrypted:
Can by more than two people as encipherer, to file multi-enciphering.
Because file has the digital signature of encipherer, relay encryption can represent that multidigit encipherer is responsible for the file submitted to thus.
The effect of business card is exactly:
When encrypting, addressee can be selected from business card;
When deciphering, system can utilize the digital signature of the public key verifications sender carried in business card.
When mouse-click visiting-card management software, visiting-card management interface will be entered.
In visiting-card management interface, can import or delete business card.
(3) file protection
(3.1) file encryption
When clicking file encryption button, file encryption interface will be entered.
One or more file can be pulled into file encryption interface.If the file pulled into is unencryption file, then corresponding operating is encryption; If encrypt file, default operation is deciphering.
After drag and drop, system can point out certification fingerprint.Each encryption all can require certification, to guarantee that I carries out file encryption at use safety system.
If authentication success, prompting is selected addressee by system.As mentioned above, can not addressee be selected, or select one or more addressee.
After selection is determined, system can point out select File storing path.If have selected the same path of source file, then encryption or declassified document can cover source file; If have selected other paths, then the file obtained can be preserved in addition.
Can also be encrypted or declassified document by following approach:
Click encryption or deciphering button, select File in the Open File dialog box ejected.Follow-up operation is the same.
Right mouse button clicks a file, and Choice encryption or deciphering in popup menu while being encrypt file (only click can be with) menu item, subsequent operation is identical.
Double mouse click encrypt file, be decrypted, follow-up operation is identical.
(3.2) file is pulverized
When clicking file and pulverizing button, file will be entered and pulverize interface.
A file icon can be dragged and dropped into file pulverizing and protect interface, to its complete deletion.
System can eject one and confirm prompting frame.
If determined, system can eject the number of times that a dialog box allows selection pulverize.After determining, file will disappear.
(5) system login
If also do not logged in, click system login button, finger print identifying prompting frame can be ejected.
After finger print identifying success, the mobile storage district of system display will switch to secure storage areas.Secret file and information can be preserved wherein.
If logged in, then after clicking this button, confirmation prompting frame can be ejected.If determined, will log off login, and visible mobile storage district comes back to general memory area.
